When we use a tensile testing machine to conduct tensile tests on materials, we inevitably encounter various problems. But if we have already repaired it and it still has various problems, then it means that we have not completely repaired it. At this point, we should conduct a comprehensive observation, inspection, and debugging of the tensile testing machine until it is completely repaired before it can continue to be put into use. So what other places are worth checking and debugging again? Let's take a look with the editor.
Check if the calibration of the load sensor is standard:
Generally, 10% or 20% of the equipment's heavy load is taken as the initial value for metrological verification, while many load sensors with poor quality happen to have larger errors below ≤ 10%. If there is indeed a problem with the accuracy of the load sensor, we should replace it in a timely manner.
Check whether the movement speed of the crossbeam is normal:
The results obtained from tensile testing vary with different speeds, therefore it is necessary to verify and verify the testing speed.
Inspection 3. Insufficient range of tensile testing machine:
Estimate whether the material strength value for tensile testing exceeds the large range of the tensile testing machine. If it exceeds the range, please replace the test material.
Check if the installation position of the displacement sensor is correct:
Due to different designs, the installation position is also different: but the one installed on the edge of the screw rod will be more accurate than the one installed on the motor.
Check whether the synchronous belt or reduction device is damaged due to the increase of usage time:
As the use time of synchronous belts or speed reduction devices increases, the aging life of these two parts will be accelerated, and failure to replace them in a timely manner will affect the test results.
Check whether the safety protection device is faulty:
If the safety protection device malfunctions, it may directly damage the instrument, and we should regularly inspect it.
